Chemical Structure

Levonorgestrel Impurity 2 CAS 850-92-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 312.40 g/mol gives Levonorgestrel Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Levonorgestrel Impurity 2 (CAS 850-92-0), a certified reference material (molecular formula C20H24O3, MW 312.40 g/mol) for analytical method development and quality control.

Structurally, Levonorgestrel Impurity 2 (C20H24O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 312.40 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Levonorgestrel Impurity 2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
